You could be missing a vas deferens. One in 500 men have perfectly normal testicles, but they have a natural vasectomy. It's congenital absence of the vas. They're going to be sterile or infertile.

It's about 10% vasofluid with sperm. It's about 80% seminal vesicle fluid, which is an accessory sex gland in the back of the prostate, and about 10% prostate. So typically during ejaculation, prostatic fluid, which is clear and sticky, will grease the barrel of the urethra pre-cum.

Then during the ejaculation process, the pellet of sperm gets pumped from the vas deferens into a chamber called the ejaculatory duct. And this happens quickly. And then the seminal vesicle, which is like a bladder, contracts, sends it into the prostatic urethra between the bladder and the outer world. There's two valves. One is the bladder neck. It closes.

And one is the urethral sphincter that we pee through. And that opens.

So in 3,000 men I've done vasectomies on in 30 years, two men have said, my volume went down. And I said, really? One of them banked sperm, and he had a semen analysis before and after, and he did go down by 15%. And he noticed it, and I said, good for you. What do you want to do now? So it can be noticeable, but not usually.

And so the color is the same, the opacity is the same, the whole process of liquefaction is the same, viscosity, et cetera.

So my fingers can feel two and a half millimeters The vas deferens is like a piano wire. I mean, it is different than anything else in the cord. I did a study, a third of my men with absent vas were only found out having procedures until I saw them. I usually just do the exam, but it is an expertise thing. Yeah, it's not like the PCP can figure this out.

You have to be doing this all day, every day. Yeah, I think you need to be trained on that. But if you're well-trained, it should be purely a physical exam.

The most common genetic disease in America is cystic fibrosis. So the big implication is these men can't conceive naturally. They have a natural vasectomy. We use sperm retrieval techniques and IVF. but they definitely have the chance of passing on cystic fibrosis to a child. Why is that?

It's a very interesting biology, but men with cystic fibrosis, the most common genetic disease in America, have no vas deferens.
